Climate Action Through Eco-Friendly Textiles a technique that conceals data into a carrier for conveying the secret message confidentially and do not show any visible marks to draw the attention of the intruders. In this study, the grayscale image is divided into non-overlapping blocks. In each block, calculates the sum of the just noticeable

Hydrogen Production from Biomass and maximum values in a block are used to embed the secret data. The visual quality and embedding capacity of the PVO method is closely related to the size of the blocks. Thus, the proposed data hiding method utilizes the modified prediction methods and integrates with Ou and Kims method to improve

Ashish Bhatnagar,Bipin K. Guptantly. More and more confidential data has been delivered and the amount will keep on increasing. How to achieve the security of confidential data delivery is a very important issue in this digital era. Data encryption may help to ensure the cipher data is difficult to decode by an unknown user but i

The notes are estimated from the activation matrix, and the estimated notes are regarded as root notes. In the existing method, one-bit watermark is embedded into the dominan

Timothy R. Carter,Stefan Fronzekragile watermarking based on the singular-spectrum analysis (SSA). The SSA is used to analyze the speech signals of which the singular spectra are extracted. The watermark (e.g., signature in-formation) is embedded into those signals by modifying some parts of the singular spectra according to the w
